Based on the sound absorption mechanism of Helmholtz Resonator,the advantage of soft tube length is fully used in the new structure,and thus the low-frequency noise can be controled easily.
提出了一种新型的宽频带共振吸声结构,该结构基于赫姆霍兹共振吸声机理,并充分利用了软管在长度上的优势,易于实现对低频噪声的控制。
A new structure which lays sound absorption materials on the surface of Helmholtz resonator with extended necks is proposed in this paper,and then the theoretical analysis and numerical simulation of its sound absorption characteristics are done.
